Comment on the stability of a system which has multiple poles on jw axis.
Eg: 1/(s-2j)^2

I think it is unstable & not marginally stable. Is nt it?

Friend when there is pole at jw-axis, then the system is marinally stable and reaches to the verge of instability when more poles are added at jw-axis.
